PADLOCK.

' SPECIFIGATICN forming part of Letters Patent No. 694,837, dated March4, 1902.

Application filed May 17, 1901.

T0 at whom it may concern:

Be it known that I, JosEPH J. CortrER, a citizen of the United States,and a resident of Bowerston, in the county of Harrison and State ofOhio, have invented a new and Improved Padlock, of which the followingis a full, clear, and exact description.

This invention relates to improvements in padlocks; and the particularobject of the invention is to provide a lock-casing so constructed as toprevent the entrance of water, thus obviating any danger of ice formingin the lock in cold weather, which would intertote with the working ofthe parts; and another object is to provide in the lock mechanism anauxiliary locking-dog for the tumblers.

I will describe a padlock embodying my invention and then point out the'novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is an interior view of the lock, showing it in locked position.Fig. 2 is a similar view, but showing the look as open. Fig. 3 is a sideelevation of the lock, and Fig. i is an edge view with the beep removed.

The lock-casing comprises opposite side walls 1 and 2, connectedtogether at one edge by a wall 3 and at the opposite edge by a wall 4,which, as here shown, is arranged inward of the edges of the oppositewalls 1 and 2, forming a recess in which the hasp 5 operates, the saidhasp being pivoted at its lower end on a pin 6. The walls 3 and 4 areconnected at the upper end by means of a top edge wall 7, and at theconjunction of the walls 3 and 7 a recess 8 is provided to receive thetongue 9 on the end of the hasp. The hasp 5 is provided with aninwardly-extended finger 10, which forms a latch the hook end of whichis designed to engage with a series of tumblers -11, mounted on a pivot12 and operated by a suitable key passed through the keyhole 13 in thebottom of the The several tumblers are held yieldingly in place by meansof springs 14:, and when the hasp 5 is released it is forced outward bymeans of a spring 15, which engages erial No. 60,718. (No model.)

at one end with said hasp and at the other end with the edge Wall 4.

In connection with the tumblers I provide an auxiliary locking devicefor the tumblers, consisting of a pivoted dog 16, pressed yield inglyupon the tumblers by means of a spring 17. On its under side this dog 16has a rib 18 for engaging with the upper'edges of the tumblers.

All of the tumblers except one are provided with hooks 19, and if anytumbler thus provided with a hook is moved beyond a certain limit thebook 19 passes over the free end of the dog 16, thus holding the dogsecurely down, and thereby preventing the disengagement of the othertumblers from the lockingfinger. Any one of the tumblers provided with ahook can therefore prevent the disengagement of all the other tumblers.This feature is to prevent picking the lockthat is to say, when a falsekey is inserted it will almost certainly strike some one of the tumblersprovided with a hook and cause the engagement of said hook upon the dog16. This will occur with every key unless the same is so formed as toengage the tumblers in .the'or der desired.

To open the lock, it is only necessary to insert the key through theopening 13 and press it against the several tumblers, which will beswung upon the pivot 12 and released from the hook end of the finger l0.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. A padlock-casing, comprising the oppo site sidewalls, the opposite edge walls, one of said edge walls being arrangedinward of the edges of the side walls and having an opening below theupper end, a hasp pivoted between the side walls below said opening, alatch-finger on said hasp adapted to pass through said opening, and atop edge wall connect ing with the opposite side edge walls, substan=tially as specified.

2. A waterproof lock, comprising a hollow casing provided exteriorlywith waterproof concaved recesses, and also provided with an 1 aperture,a movable hasp provided with terminals engaging said waterproof ooncavedrecesses, a locking-finger located 111136111106.h-

ate of said terminals and extending through said aperture into saidcasing so as to form a water-tight engagement therewith, saidlocking-finger being provided with an enlargement for preventing itsWithdrawal from said casing, and means, controllable bya key, forsecuring said locking-finger in a definite position relative to saidcasing.

3. A waterproof lock, comprising a waterproof casing, a hasp providedwith a lockingfinger integral therewith, said hasp being pivoted at thebottom of said casing and said locking-finger entering the side thereofand provided with a lug inside of said casing, a dog pivoted inside ofsaid casing, and a series of tumblers some of which are provided withoppositely-disposed hooks to engage, respectively, said dog and said lugupon said locking-finger.

4. A look, comprising a casing, a hasp provided with a locking-finger,aplurality of tumblers provided with shoulders, and a dog provided witha flat face and a transverse rib for engaging different surfaces of saidtumblers.

5. A lock, comprising a casing, a hasp provided with a locking-finger,apluralityof tun1- blers provided with edges disposed at differentangles and with shoulders, and a dog provided with a flat face and atransverse rib for engaging said edges respectively.

In testimony whereof- I have signed my name to this specification in thepresence of two subscribing witnesses.
